Our Cohorts continue to increase and attract new participants.  Some formed many years ago while others are just being added by new members. Cohorts are usually defined as “a group of people banded together” or “a group of people with a common characteristic.” Each of our Cohorts is a brainchild of one of our members and ranges from Poker and Cinema to Rosh Chodesh and Mussar.  You do not need to be a member to participate in our cohorts although we would greatly appreciate a membership contribution.  In JCo’s case, we cohorts come together as Jews with common passions and talents and enjoy each others’ company.

Cohort members create memories and experiences thereby creating a community that enjoys being Jewish together while being productive. 

If you would like to join or start a cohort please contact

  • ROSH CHODESH Cohort led by Gabi & Tirza Arad. This cohort is for women only. It started with a small group and grew to include many of us.  Rosh Chodesh, the first of each Jewish month is the celebration of the new moon, its slender crescent barely visible in the night sky.  This day is historically associated with women’s renewal and celebration. Some say that this is because the women of Israel did not offer their jewelry for the creation of the Golden Calf. As a result, they were given Rosh Chodesh as a day when they could abstain from work. To this day, some women refrain from some forms of labor on Rosh Chodesh. Others have connected the waxing and waning of the moon to a woman’s menstrual cycle. Whatever the reason, Rosh Chodesh has long been a time for Jewish women to gather for a wide variety of activities, from reciting traditional liturgy, to sharing a meal (or a glass of wine), discussing Jewish ethics, and working for social change.  Please refer to the JCo virtual calendar for details.
